Supergravity with one auxiliary spinor

We present an “intermediate” off-shell version of N = 1 supergravity and its tensor calculus. The supergravity multiplet has 16 + 16 field components. The formulation can be constrained to either of the minimal ones with 12 + 12 components, or enlarge by matter couplings to several 20 + 20 component versions. Self-coupled to its own axial gauge submultiplet it leads to spontaneous supersymmetry breaking in the form first discussed by Freedman and to a propagating gauge field.
